In a future where cities have crumbled and been reclaimed by nature we join a lone man exploring the ruins of the company Haven Nanosystems. Recovering a locked container he seems to have found what he was looking for, which is information relating to the quarantined Facility B. Unfortunately just as located by a robotic drone and the race to escape is on. 蓝天白云，植被叠嶂。故事发生在不知过了几百年几千年后的地球。也不知道因为什么原因，人类文明消失殆尽。曾经的繁华都市变成废墟，高楼大厦依然矗立，但都被绿色植物所覆盖，成为了无生气的古文明建筑。某座摩天大厦，一名戴着面罩的男子鼓捣出一个铁箱子，里面藏着旧文明的东西。就在此时，天空中响起了引擎轰鸣声，一架悬停飞机出现在他的头顶上。男人见状不好，连忙迅速跑开，骑上停在一边的摩托夺路逃亡，而空中的飞机则紧追不舍，甚至发射了跟踪导弹。 追逐仍在继续，而今的地球仍然没有回复宁静……
